Images are registered by moving one image right, left, up, or down, relative
to the other images. Registration is useful for taking jitter out of movies
and adjusting stereo pairs for the best effect. Use these buttons in the
Data Cube Tool to register images:

How to register a Stereo
Pair

A stereo pair of images can be registered,
cropped, rotated, and the brightness and contrast adjusted with the CLUT sliders.
All of this is done with the Data Cube Tool. In this case, the 'cube'
is only two layers thick: Here are the steps:

Load the images into a data cube using Read / as image files.
(This is the Read button in the Data cube tool.) Select the
images and open them.

Note that the slice slider will show one image or the other. You can
see the stereo rotation effect just by wiggling the slice slider to display
one image or the other.

Select the cube with the Cube! button.

Select one image with the slice slider. Click ref slc!
Then select the other image and click flick slc! This
seems superfluous here, as there are only two images in the cube, but it is
necessary with more than two images.

Start the flickering by clicking on!

Move one of the images relative to the other by clicking and dragging on
the flickering cube.

Use the jog buttons
to move the flicker image one pixel at a time in any direction.

Make a new cube with the images registered as you see them now: Cube
/ register using offsets.

Rotate if necessary. Open the Profile Tool, select the cube, put the
line along the apparent axis of rotation, then use Cube /
rotate using profile tool.

Adjust the brightness or contrast, e.g. with CLUT / gamma slider
on one or the other slices, then use Propigate / fix to LUT.

Open the '2 & 3 variable Tool. Select one image
with the slice slider for the cube, and click 'red / x' to
selec it as the red image. Select the other image as the green image
and blue image. Then use RGB overlay / make rgb overlay.

How to
register a data cube and make a stereo movie GIF file:

(Note - some of this is outdated because
the Data Cube Tool has been changed a little. These register functions
still work, but using the Offsets and Tracking
buttons is much faster, and almost as tood. Registration can then be
refined using some of the steps below.) Here are the steps in detail:

1) Load the original data
into a cube.

a) The files probably
should be sorted by their write date/time. See 'Sort
Method' in the File Utilities Tool.
